Full migration to IPv6 brings the need to adjust datacommunication services for the new generationof IP protocols with maintained or expanded functionality. This thesis’ goals is to submitone or more solutions that meets requirements and the technical conditions that enables thecompany DGC:s to expand the service IP-VPN for IPv6. This includes address assignmenttechniques like prefix delegation and automatic address configuration in existing network infrastructure.Solutions are presented in six scenarios that have been investigated considering tests, analysis andexperienced problems. The investigation formed the criteria scalability, configuration complexity,compatibility, support by RFC:s and requirements stated by DGC that adds to the evaluationof the most suitable solution.The evaluation has resulted in a recommended scenario that is implementable according to givengoals.Techniques that may influence the choice of most suitable solution, but that is not yet available,are discussed and presented to point out what may needed to be considered in the future.
